RUNH and its subsidiary, RUNH TG Co., Ltd., have jointly launched a number of steam turbine retrofit technologies, including steam turbine capacity retrofit, steam turbine energy-saving retrofit, steam turbine island system retrofit, steam turbine heating retrofit, and many other unit retrofit technologies. Here is the profile of Runh’s turbine design and manufacturing company — RUNH TG Co., Ltd., formerly a subsidiary of the Chinese Academy of Sciences (CAS). Based on scientific research achievements in turbomachinery aerodynamics and thermodynamics from the Institute of Engineering Thermophysics under CAS, and in cooperation with other founding shareholders such as Tsinghua University, Beihang University, and other research institutes and manufacturing enterprises, RUNH TG has explored the integration of industry, academia, and research for over 20 years. Through these efforts, the company has developed steam turbine design technologies with independent intellectual property rights and contemporary advanced standards, successfully achieving industrialization and market application.
RUNH can carry out technical retrofits for both Russian-made and domestic turbines. Through optimization of steam turbine flow design, the heat consumption of the unit can be reduced by 5–7%, and coal consumption can be reduced by 15–21 g/kWh (up to 30 g/kWh for Russian units). The company has completed hundreds of retrofit projects, achieving thermal performance that meets modern advanced standards.
